The Vacon NXS is a compact AC drive in the power range of 0.37-560 kW and supply voltages of 208-690 V for heavy use in machines, buildings and all branches of industry. The robust design incorporates effective protection against supply network disturbances. Trip-free operation is also guaranteed due to sophisticated motor control principles and motor/drive protection features, component selection and effective cooling. The reliable choice Enclosure classes of IP21 and IP54 and integrated high-level EMC filters make the Vacon NXS suitable for all environments. The

Start-Up Wizard and the standard All-In-One Application Package make parameter setting extremely easy in all cases, from simple to complex. The wide and flexible standard I/O and option for five I/O boards provide versatile controllability. The most common fieldbus options are also available. The modular design of the Vacon NXS brings several advantages: the control terminals are safely separated from power terminals, upgrading the control inputs and outputs is easy and convenient, replacing the cooling fan (the only regularly replaceable component) is fast, the display panel can be utilized for parameter copying, etc. The robust drive for heavy use Easy to use display panel Start-Up Wizard All-in-One Application Package Versatile PID controller and pump automatic for 1-5 pumps Special applications available (water control, high speed, etc.) Five slots for control boards (2 basic boards and 3 option boards) High switching frequency, low noise Steady state speed error < 1% Low torque ripple Starting torque > 200%, depending on AC drive sizing Suitable for multi-motor applications Design & Dimensions The mechanical design is extremely compact. The IP54 units in particular are the smallest AC drives on the market. All units are suitable for both wall and enclosure mounting with all necessary components: integrated EMC filters, AC chokes, cable protection, dust and water protection. The effective super-cooling principle allows high ambient temperatures and high switching frequencies without de-rating. Vacon NXS control unit There are no fixed inputs or outputs in the Vacon NXS. There are five slots (A, B, C, D and E) for I/O boards, and a suitable board can be selected for each slot. The NXS units are delivered with OPT-A1 and OPT-A2 boards if the I/O is not specified. In many countries, boards OPT-A1 and OPT-A3 are used as standard I/O as the galvanically (double) isolated thermistor input is often required. Removable terminals, snap-in card installation, automatic card identification and instructions on the drive help making quick connections. If necessary, the inputs, outputs and fieldbus boards can be added in the field. The Vacon NXS is simply the most flexible frequency converter series on the market. An external +24 V supply option enables communication with the control unit even if the mains supply is switched off (e.g. fieldbus communication and parameter settings).
